The Troy Lee Designs D4 AS Carbon full-face helmet in Frames Black / Gold is the choice of downhill and freeride racers at the highest level. A featherweight carbon shell carries MIPS C2 rotational protection, an EPP chin bar and anatomical 3D cheek pads with an emergency release system. Three shell sizes give a precise fit across head shapes, titanium D-rings cut weight, and a washable moisture-wicking liner keeps it fresh between race runs. Certified to ASTM F1952 downhill, CPSC 1203 and CE EN 1078, this is a World Cup-proven DH helmet for riders who want the best.
